In His Anti-darwinian Book... (and Eponymously Named The Neck Of The Giraffe ), Francis Hitching Tells The Story... "the Need To Survive By Reaching Ever Higher For Food Is, Like So Many Darwinian Explanations Of Its Kind, Little More Than A Post Hoc Speculation."

All Interesting Issues In Natural History Are Questions Of Relative Frequency, Not Single Examples. Everything Happens Once Amidst The Richness Of Nature. But When An Unanticipated Phenomenon Occurs Again And Again—finally Turning Into An Expectation—then Theories Are Overturned.

We Are Storytelling Animals, And Cannot Bear To Acknowledge The Ordinariness Of Our Daily Lives.

The Extreme Rarity Of Transitional Forms In The Fossil Record Persists As A Trade Secret Of Paleontology. Evolutionary Trees That Adorn Our Textbooks Have Data Only At The Tips And Nodes Of Their Branches; The Rest Is Inference, However Reasonable, Not The Evidence Of Fossils.

Evolving Life Must Experience A Vast Range Of Possibilities, Based On Environmental Histories So Unpredictable That No Realized Route - The Pathway To Consciousness In The Form Of Homo Sapiens Or Little Green Men, For Example - Can Be Construed As A Highway To Heaven, But Must Be Viewed As A Tortuous Track Rutted With Uncountable Obstacles And Festooned With Innumerable Alternative Branches. Any Reasonably Precise Repetition Of Our Earthly Route On Another Planet Therefore Becomes Wildly Improbable Even In A Trillion Cases.

Any Human Being Is Really Good At Certain Things. The Problem Is That The Things You're Good At Come Naturally. And Since Most People Are Pretty Modest Instead Of An Arrogant S.o.b. Like Me, What Comes Naturally, You Don't See As A Special Skill. It's Just You. It's What You've Always Done.

Contingency Is Rich And Fascinating; It Embodies An Exquisite Tension Between The Power Of Individuals To Modify History And The Intelligible Limits Set By Laws Of Nature. The Details Of Individual And Species's Lives Are Not Mere Frills, Without Power To Shape The Large-scale Course Of Events, But Particulars That Can Alter Entire Futures, Profoundly And Forever.

We Can Now Determine, Easily And Relatively Cheaply, The Detailed Chemical Architecture Of Genes ; And We Can Trace The Products Of These Genes ( Enzymes And Proteins ) As They Influence The Course Of Embryology . In So Doing We Have Made The Astounding Discovery That All Complex Animal Phyla - Arthropods And Vertebrates In Particular - Have Retained, Despite Their Half-billion Years Of Evolutionary Independence, An Extensive Set Of Common Genetic Blueprints For Building Bodies.

The Board Transported Its Jurisdiction To A Never-never Land Where A Dorothy Of The New Millennium Might Exclaim: "they Still Call It Kansas, But I Don't Think We're In The Real World Anymore."

When Scientists Need To Explain Difficult Points Of Theory, Illustration By Hypothetical Example - Rather Than By Total Abstraction - Works Well (perhaps Indispensably) As A Rhetorical Device. Such Cases Do Not Function As Speculations In The Pejorative Sense - As Silly Stories That Provide Insight Into Complex Mechanisms - But Rather As Idealized Illustrations To Exemplify A Difficult Point Of Theory. (other Fields, Like Philosophy And The Law, Use Such Conjectural Cases As A Standard Device.

The Most Erroneous Stories Are Those We Think We Know Best - And Therefore Never Scrutinize Or Question.

The Contingency Of History (both For Life In General And For The Cultures Of Homo Sapiens ) And Human Free Will (in The Factual Rather Than Theological Sense) Are Conjoined Concepts, And No Better Evidence Can Be Produced Than The "experimental" Production Of Markedly Different Solutions In Identical Environments.

Skepticism Is The Agent Of Reason Against Organized Irrationalism--and Is Therefore One Of The Keys To Human Social And Civic Decency.

Nothing Is More Dangerous Than A Dogmatic Worldview - Nothing More Constraining, More Blinding To Innovation, More Destructive Of Openness To Novelty.

As In 1925, Creationists Are Not Battling For Religion. They Have Been Disowned By Leading Church Men Of All Persuasions, For They Debase Religion Even More Than They Misconstrue Science. They Are A Motley Collection To Be Sure, But Their Core Of Practical Support Lies With The Evangelical Right, And Creationism Is A Mere Stalking Horse Or Subsidiary Issue In A Political Program...the Enemy Is Not Fundamentalism; It Is Intolerance. In This Case, The Intolerance Is Perverse Since It Masquerades Under The 'liberal' Rhetoric Of 'equal Time'.

What An Odd Time To Be A Fundamentalist About Adaptation And Natural Selection - When Each Major Subdiscipline Of Evolutionary Biology Has Been Discovering Other Mechanisms As Adjuncts To Selection's Centrality.

Human Life Is The Result Of A Glorious Evolutionary Accident.

The History Of Life Is A Tale Of Decimation And Later Stabilization Of Few Surviving Anatomies, Not A Story Of Steady Expansion And Progress.

The Essence Of Darwinism Lies In Its Claim That Natural Selection Creates The Fit. Variation Is Ubiquitous And Random In Direction. It Supplies Raw Material Only. Natural Selection Directs The Course Of Evolutionary Change.

When We Look To Presumed Sources Of Origin For Competing Evolutionary Explanations Of The Giraffe's Long Neck, We Find Either Nothing At All, Or Only The Shortest Of Speculative Conjectures. Length, Of Course, Need Not Correspond With Importance. Garrulous Old Polonius , In A Rare Moment Of Clarity, Reminded Us That "brevity Is The Soul Of Wit" (and Then Immediately Vitiated His Wise Observation With A Flood Of Woolly Words About Hamlet 's Madness.

Nothing Matches The Holiness And Fascination Of Accurate And Intricate Detail.

It's True That The Level Of Scientific Knowledge Among Adults Is Very Low, But That's Not Because There Isn't A Natural Interest. I Think Most Kids Are Fascinated By The Natural World. I've Often Said That If You Could Quantify The Mental Power Involved In All The Dinosaur Names Correctly Known And Correctly Spelled By 5-year-old Kids In America, You Could Move Any Mountain On Earth.

I Don't Think Academic Writing Ever Was Wonderful. However, Science Used To Be Much Less Specialized.

Theory-free Science Makes About As Much Sense As Value-free Politics.

I Am Particularly Fond Of [emmanuel Mendes Da Costa's] Natural History Of Fossils Because This Treatise, More Than Any Other Work Written In English, Records A Short Episode Expressing One Of The Grand False Starts In The History Of Natural Science And Nothing Can Be Quite So Informative And Instructive As A Juicy Mistake.

The Median Isn't The Message.

The Real Tragedy Of Human Existence Is Not That We Are Nasty By Nature, But That A Cruel Structural Asymmetry Grants To Rare Events Of Meanness Such Power To Shape Our History.

Organisms Are Not Billiard Balls, Propelled By Simple And Measurable External Forces To Predictable New Positions On Life's Pool Table. Sufficiently Complex Systems Have Greater Richness. Organisms Have A History That Constrains Their Future In Myriad, Subtle Ways.

Obsolescence Is A Fate Devoutly To Be Wished, Lest Science Stagnate And Die.

Orchids Manufacture Their Intricate Devices From The Common Components Of Ordinary Flowers, Parts Usually Fitted For Very Different Functions. If God Had Designed A Beautiful Machine To Reflect His Wisdom And Power, Surely He Would Not Have Used A Collection Of Parts Generally Fashioned For Other Purposes. Orchids Were Not Made By An Ideal Engineer; They Are Jury-rigged From A Limited Set Of Available Components. Thus, They Must Have Evolved From Ordinary Flowers.

There Is No Gene "for" Such Unambiguous Bits Of Morphology As Your Left Kneecap Or Your Fingernail. [...] Hundreds Of Genes Contribute To The Building Of Most Body Parts And Their Action Is Channeled Through A Kaleidoscopic Series Of Environmental Influences: Embryonic And Postnatal, Internal And External. Parts Are Not Translated Genes, And Selection Doesn't Even Work Directly On Parts.

Evolution Is A Process Of Constant Branching And Expansion.

Misunderstanding Of Probability May Be The Greatest Of All Impediments To Scientific Literacy.

True Majorities, In A Tv-dominated And Anti-intellectual Age, May Need Sound Bites And Flashing Lights And I Am Not Against Supplying Such Lures If They Draw Children Into Even A Transient Concern With Science. But Every Classroom Has One [oliver] Sacks , One [eric] Korn, Or One [jonathan] Miller , Usually A Lonely Child With A Passionate Curiosity About Nature, And A Zeal That Overcomes Pressures For Conformity. Do Not The One In Fifty Deserve Their Institutions As Well Magic Places, Like Cabinet Museums, That Can Spark The Rare Flames Of Genius?

I Believe That We Can Still Have A Genre Of Scientific Books Suitable For And Accessible Alike To Professionals And Interested Laypeople. The Concepts Of Science, In All Their Richness And Ambiguity, Can Be Presented Without Any Compromise, Without Any Simplification Counting As Distortion, In Language Accessible To All Intelligent People. I Hope That This Book Can Be Read With Profit Both In Seminars For Graduate Students And If The Movie Stinks And You Forgot Your Sleeping Pills On The Businessman's Special To Tokyo.

Not Since The Lord Himself Showed His Stuff To Ezekiel In The Valley Of Dry Bones Had Anyone Brought Such Grace And Skill To The Reconstruction Of Animals From Disarticulated Skeletons. Charles R. Knight, Most Celebrated Of Artists In The Reanimation Of Fossils, Painted All The Canonical Figures Of Dinosaurs That Fire Our Fear And Imagination To This Day.

Among People I Have Met, The Few Whom I Would Term “great” All Share A Kind Of Unquestioned, Fierce Dedication; An Utter Lack Of Doubt About The Value Of Their Activities (or At Least An Internal Impulse That Drives Through Any Such Angst); And Above All, A Capacity To Work (or At Least To Be Mentally Alert For Unexpected Insights) At Every Available Moment Of Every Day Of Their Lives.

Theory And Fact Are Equally Strong And Utterly Interdependent; One Has No Meaning Without The Other. We Need Theory To Organize And Interpret Facts, Even To Know What We Can Or Might Observe. And We Need Facts To Validate Theories And Give Them Substance.

For Dawkins, Evolution Is A Battle Among Genes, Each Seeking To Make More Copies Of Itself. Bodies Are Merely The Places Where Genes Aggregate For A Time.

Zoocentrism Is The Primary Fallacy Of Human Sociobiology, For This View Of Human Behavior Rests On The Argument That If The Actions Of "lower" Animals With Simple Nervous Systems Arise As Genetic Products Of Natural Selection, Then Human Behavior Should Have A Similar Basis.

The Most Important Scientific Revolutions All Include, As Their Only Common Feature, The Dethronement Of Human Arrogance From One Pedestal After Another Of Previous Convictions About Our Centrality In The Cosmos.

Orchids Were Not Made By An Ideal Engineer; They Are Jury-rigged From A Limited Set Of Available Components.

We Have Become, By The Power Of A Glorious Evolutionary Accident Called Intelligence, The Stewards Of Life's Continuity On Earth. We Did Not Ask For This Role, But We Cannot Abjure It. We May Not Be Suited To It, But Here We Are.

Science Can't Tell Us What Our Life Means Ethically. It Can't Tell Us What We Are Meant To Do As Moral Creatures. But, Insofar As Science Can Understand What We're Made Of, And What We're Related To, The Darwinian Revolution Completely Revised Our Ideas About Who We Are And What We're Related To And How Long We've Been Here And Why We're On This Earth.

When We Seek A Textbook Case For The Proper Operation Of Science, The Correction Of Certain Error Offers Far More Promise Than The Establishment Of Probable Truth. Confirmed Hunches, Of Course, Are More Upbeat Than Discredited Hypotheses. Since The Worst Traditions Of "popular" Writing Falsely Equate Instruction With Sweetness And Light, Our Promotional Literature Abounds With Insipid Tales In The Heroic Mode, Although Tough Stories Of Disappointment And Loss Give Deeper Insight Into A Methodology That The Celebrated Philosopher Karl Popper Once Labeled As "conjecture And Refutation.

Great Theories Are Expansive; Failures Mire Us In Dogmatism And Tunnel Vision.

All Science Is Intelligent Inference; Excessive Literalism Is Delusion, Not A Humble Bowing To Evidence.

I Would Rather Label The Whole Enterprise Of Setting A Biological Value Upon Groups For What It Is: Irrelevant, Intellectually Unsound, And Highly Injurious.

Mass Extinctions May Not Threaten Distant Futures, But They Are Decidedly Unpleasant For Species Caught Up In The Throes Of Their Power.

Mass Extinction

We Live In A Profoundly Nonintellectual Culture, Made All The Worse By A Passive Hedonism Abetted By The Spread Of Wealth And Its Dissipation Into Countless Electronic Devices That Impart The Latest In Entertainment And Supposed Information - All In Short (and Loud) Doses Of "easy Listening".

Paleontologists [fossil Experts] Have Paid An Exorbitant Price For Darwin's Argument. We Fancy Ourselves As The Only True Students Of Life's History, Yet To Preserve Our Favored Account Of Evolution By Natural Selection We View Our Data As So Bad That We Almost Never See The Very Process We Profess To Study.

Our Current Drug Crisis Is A Tragedy Born Of A Phony System Of Classification. For Reasons That Are Little More Than Accidents Of History, We Have Divided A Group Of Nonfood Substances Into Two Categories: Items Purchasable For Supposed Pleasure (such As Alcohol), And Illicit Drugs.

I Emphatically Do Not Assert The General 'truth' Of This Philosophy Of Punctuational Change. Any Attempt To Support The Exclusive Validity Of Such A Grandiose Notion Would Border On The Nonsensical.

World Views Are Social Constructions And They Channel The Search For Facts. But Facts Are Found And Knowledge Progresses, However Fitfully.

Look In The Mirror, And Don't Be Tempted To Equate Transient Domination With Either Intrinsic Superiority Or Prospects For Extended Survival.

We Are Here Because One Odd Group Of Fishes Had A Peculiar Fin Anatomy That Could Transform Into Legs For Terrestrial Creatures; Because The Earth Never Froze Entirely During An Ice Age; Because A Small And Tenuous Species, Arising In Africa A Quarter Of A Million Years Ago, Has Managed, So Far, To Survive By Hook And By Crook. We May Yearn For A ‘higher Answer’– But None Exists

We Debase The Richness Of Both Nature And Our Own Minds If We View The Great Pageant Of Our Intellectual History As A Compendium Of New Information Leading From Primal Superstition To Final Exactitude. We Know That The Sun Is Hub Of Our Little Corner Of The Universe, And That Ties Of Genealogy Connect All Living Things On Our Planet, Because These Theories Assemble And Explain So Much Otherwise Disparate And Unrelated Information Not Because Galileo Trained His Telescope On The Moons Of Jupiter Or Because Darwin Took A Ride On A Galápagos Tortoise.

As A Graduate Student At Columbia University, I Remember The A Priori Derision Of My Distinguished Stratigraphy Professor Toward A Visiting Australian Drifter [a Supporter Of The Theory Of Continental Drift]. Today My Own Students Would Dismiss With Even More Derision Anyone Who Denied The Evident Truth Of Continental Drift - A Prophetic Madman Is At Least Amusing; A Superannuated Fuddy-duddy Is Merely Pitiful.

But Our Ways Of Learning About The World Are Strongly Influenced By The Social Preconceptions And Biased Modes Of Thinking That Each Scientist Must Apply To Any Problem. The Stereotype Of A Fully Rational And Objective Scientific Method, With Individual Scientists As Logical (and Interchangeable) Robots, Is Self-serving Mythology.

It Is The Things We Think We Know - Because They Are So Elementary Or Because They Surround Us - That Often Present The Greatest Difficulties When We Are Actually Challenged To Explain Them.

Darwin's Principle Of Natural Selection Leads To The Prediction That The Proper Way To Analyze Any Evolutionary Development Is To See The New Features As Adaptive To Environments. And That's A Perfectly Good Principle. The Problem Is That There Are Many Evolutionary Biologists Who View Everything That Happens In Evolution As Directly Evolved For Adaptive Benefit. And That Just Doesn't Work. Whenever You Build A Structure For Adaptive Reasons, The Structure Is Going To Exhibit Properties That Have Nothing To Do With Adaptation. They're Just Side Consequences.

Life Is A Copiously Branching Bush, Continually Pruned By The Grim Reaper Of Extinction, Not A Ladder Of Predictable Progress.

I Am, Somehow, Less Interested In The Weight And Convolutions Of Einstein’s Brain Than In The Near Certainty That People Of Equal Talent Have Lived And Died In Cotton Fields And Sweatshops.

Our Creationist Detractors Charge That Evolution Is An Unproved And Unprovable Charade — A Secular Religion Masquerading As Science. They Claim, Above All, That Evolution Generates No Predictions, Never Exposes Itself To Test, And Therefore Stands As Dogma Rather Than Disprovable Science. This Claim Is Nonsense.

My Own Field Of Paleontology Has Strongly Challenged The Darwinian Premise That Life's Major Transformations Can Be Explained By Adding Up, Through The Immensity Of Geological Time, The Successive Tiny Changes Produced Generation After Generation By Natural Selection.

Some Beliefs May Be Subject To Such Instant, Brutal And Unambiguous Rejection. For Example: No Left-coiling Periwinkle Has Ever Been Found Among Millions Of Snails Examined. If I Happen To Find One During My Walk On Nobska Beach Tomorrow Morning, A Century Of Well Nurtured Negative Evidence Will Collapse In An Instant.

We Who Revel In Nature's Diversity And Feel Instructed By Every Animal Tend To Brand Homo Sapiens As The Greatest Catastrophe Since The Cretaceous Extinction.

Biological Determinism Is, In Its Essence, A Theory Of Limits. It Takes The Current Status Of Groups As A Measure Of Where They Should And Must Be ... We Inhabit A World Of Human Differences And Predilections, But The Extrapolation Of These Facts To Theories Of Rigid Limits Is Ideology.

It Seems The Height Of Antiquated Hubris To Claim That The Universe Carried On As It Did For Billions Of Years In Order To Form A Comfortable Abode For Us. Chance And Historical Contingency Give The World Of Life Most Of Its Glory And Fascination. I Sit Here Happy To Be Alive And Sure That Some Reason Must Exist For "why Me?" Or The Earth Might Have Been Totally Covered With Water, And An Octopus Might Now Be Telling Its Children Why The Eight-legged God Of All Things Had Made Such A Perfect World For Cephalopods.

In The Great Debates Of Early-nineteenth Century Geology, Catastrophists Followed The Stereotypical Method Of Objective Science-empirical Literalism. They Believed What They Saw, Interpolated Nothing, And Read The Record Of The Rocks Directly.

Life Began Three And A Half Billion Years Ago, Necessarily About As Simple As It Could Be, Because Life Arose Spontaneously From The Organic Compounds In The Primeval Oceans.

Forelimbs Of People, Porpoises, Bats And Horses Provide The Classic Example Of Homology In Most Textbooks. They Look Different, And Do Different Things, But Are Built Of The Same Bones. No Engineer, Starting From Scratch Each Time, Would Have Built Such Disparate Structures From The Same Parts.

I Strongly Reject Any Conceptual Scheme That Places Our Options On A Line, And Holds That The Only Alternative To A Pair Of Extreme Positions Lies Somewhere Between Them. More Fruitful Perspectives Often Require That We Step Off The Line To A Site Outside The Dichotomy.

Human Consciousness Arose But A Minute Before Midnight On The Geological Clock. Yet We Mayflies Try To Bend An Ancient World To Our Purposes, Ignorant Perhaps Of The Messages Buried In Its Long History. Let Us Hope That We Are Still In The Early Morning Of Our April Day.

Death Is The Ultimate Enemy - And I Find Nothing Reproachable In Those Who Rage Mightily Against The Dying Of The Light.

Evolution Is An Obstacle Course Not A Freeway; The Correct Analogue For Long-term Success Is A Distant Punt Receiver Evading Legions Of Would-be Tacklers In An Oddly Zigzagged Path Toward A Goal, Not A Horse Thundering Down The Flat.

Everything Comes To Us In Fifteen-second Sound Bites And Photo Opportunities. All Possibility For Ambiguity - The Most Precious Trait Of Any Adequate Analysis - Is Erased.

If There Is Any Consistent Enemy Of Science, It Is Not Religion, But Irrationalism.

Iconography Becomes Even More Revealing When Processes Or Concepts, Rather Than Objects, Must Be Depicted For The Constraint Of A Definite "thing" Cedes Directly To The Imagination. How Can We Draw "evolution" Or "social Organization," Not To Mention The More Mundane "digestion" Or "self-interest," Without Portraying More Of A Mental Structure Than A Physical Reality? If We Wish To Trace The History Of Ideas, Iconography Becomes A Candid Camera Trained Upon The Scholar's Mind.

Without A Commitment To Science And Rationality In Its Proper Domain, There Can Be No Solution To The Problems That Engulf Us. Still, The Yahoos Never Rest.

The Causes Of Life's History [cannot] Resolve The Riddle Of Life's Meaning.

The History Of Life Is More Adequately Represented By A Picture Of 'punctuated Equilibria' Than By The Notion Of Phyletic Gradualism. The History Of Evolution Is Not One Of Stately Unfolding, But A Story Of Homeostatic Equilibria, Disturbed Only 'rarely' (i.e. Rather Often In The Fullness Of Time) By Rapid And Episodic Events Of Speciation.

Advocates For A Single Line Of Progress Encounter Their Greatest Stumbling Block When They Try To Find A Smooth Link Between The Apparently Disparate Designs Of The Invertebrates And Vertebrates.

Creation Science Has Not Entered The Curriculum For A Reason So Simple And So Basic That We Often Forget To Mention It: Because It Is False, And Because Good Teachers Understand Why It Is False. What Could Be More Destructive Of That Most Fragile Yet Most Precious Commodity In Our Entire Intellectual Heritage-good Teaching-than A Bill Forcing Our Honorable Teachers To Sully Their Sacred Trust By Granting Equal Treatment To A Doctrine Not Only Known To Be False, But Calculated To Undermine Any General Understanding Of Science As An Enterprise?.

A Man Does Not Attain The Status Of Galileo Merely Because He Is Persecuted; He Must Also Be Right.

Natural Selection Is Just Three Factors - Over-production, Variation, And Inheritance Combined To Produce Adaptation To Changing Local Environments. It's Not A Principle Or Progress; It's Just A Principle Of Local Adaptation. You Don't Make Better Creatures In Any Cosmic Sense; You Make Creatures That Are Better Suited To The Changing Climates Of Their Local Habitats.

I Am Not, Personally, A Believer Or A Religious Man In Any Sense Of Institutional Commitment Or Practice. But I Have A Great Respect For Religion, And The Subject Has Always Fascinated Me, Beyond Almost All Others (with A Few Exceptions, Like Evolution And Paleontology).

We Build Our Personalities Laboriously And Through Many Years, And We Cannot Order Fundamental Changes Just Because We Might Value Their Utility; No Button Reading "positive Attitude" Protrudes From Our Hearts, And No Finger Can Coerce Positivity Into Immediate Action By A Single And Painless Pressing.

Throughout His Last Half-dozen Books, For Example, Arthur Koestler Has Been Conducting A Campaign Against His Own Misunderstanding Of Darwinism. He Hopes To Find Some Ordering Force, Constraining Evolution To Certain Directions And Overriding The Influence Of Natural Selection. [...] Darwinism Is Not The Theory Of Capricious Change That Koestler Imagines. Random Variation May Be The Raw Material Of Change, But Natural Selection Builds Good Design By Rejecting Most Variants While Accepting And Accumulating The Few That Improve Adaptation To Local Environments.

Taxonomy (the Science Of Classification) Is Often Undervalued As A Glorified Form Of Filing-with Each Species In Its Folder, Like A Stamp In Its Prescribed Place In An Album; But Taxonomy Is A Fundamental And Dynamic Science, Dedicated To Exploring The Causes Of Relationships And Similarities Among Organisms. Classifications Are Theories About The Basis Of Natural Order, Not Dull Catalogues Compiled Only To Avoid Chaos.

The Intricate And Different Life Cycles Of Both Male And Female Root-heads, And The Great Behavioral Sophistication Shown By The Female In Reconfiguring A Host Crab As A Support System, All Underscore The Myopia Of Our Conventional Wisdom In Regarding Rhizocephalans As Degenerate Parasites Because The Adult Anatomy Of Internal Roots And External Sac Seem So Simple.

All Evolutionary Biologists Know That Variation Itself Is Nature's Only Irreducible Essence... I Had To Place Myself Amidst The Variation.

Few Intellectual Tyrannies Can Be More Recalcitrant Than The Truths That Everybody Knows And Nearly No One Can Defend With Any Decent Data (for Who Needs Proof Of Anything So Obvious). And Few Intellectual Activities Can Be More Salutary Than Attempts To Find Out Whether These Rocks Of Ages Might Crumble At The Slightest Tap Of An Informational Hammer.

What You See Is That The Most Outstanding Feature Of Life's History Is A Constant Domination By Bacteria.

The Human Mind Delights In Finding Pattern—so Much So That We Often Mistake Coincidence Or Forced Analogy For Profound Meaning. No Other Habit Of Thought Lies So Deeply Within The Soul Of A Small Creature Trying To Make Sense Of A Complex World Not Constructed For It.

You Put Three Facts Together - That All Organisms Produce More Offspring That Can Survive, That There's Variation Among Organisms, And That At Least Some Of That Variation Is Inherited - And The Syllogistic Inference Is Natural Selection.

Goethe Died In 1832. As You Know, Goethe Was Very Active In Science. In Fact, He Did Some Very Good Scientific Work In Plant Morphology And Mineralogy. But He Was Quite Bitter At The Way In Which Many Scientists Refused To Grant Him A Hearing Because He Was A Poet And Therefore, They Felt, He Couldn't Be Serious.

We May Need Simple And Heroic Legends For That Peculiar Genre Of Literature Known As The Textbook. But Historians Must Also Labor To Rescue Human Beings From Their Legends In Science If Only So That We May Understand The Process Of Scientific Thought Aright.

It Has Become, In My View, A Bit Too Trendy To Regard The Acceptance Of Death As Something Tantamount To Intrinsic Dignity. Of Course I Agree With The Preacher Of Ecclesiastes That There Is A Time To Love And A Time To Die - And When My Skein Runs Out I Hope To Face The End Calmly And In My Own Way. For Most Situations, However, I Prefer The More Martial View That Death Is The Ultimate Enemy - And I Find Nothing Reproachable In Those Who Rage Mightily Against The Dying Of The Light.

A Complete Theory Of Evolution Must Acknowledge A Balance Between "external" Forces Of Environment Imposing Selection For Local Adaptation And "internal" Forces Representing Constraints Of Inheritance And Development. Vavilov Placed Too Much Emphasis On Internal Constraints And Downgraded The Power Of Selection. But Western Darwinians Have Erred Equally In Practically Ignoring (while Acknowledging In Theory) The Limits Placed On Selection By Structure And Development What Vavilov And The Older Biologists Would Have Called "laws Of Form.

Theory Of Evolution

I Hardly Recognize What I Do Well. I Just Do It.

[g]enes Make Enzymes, And Enzymes Control The Rates Of Chemical Processes. Genes Do Not Make "novelty Seeking" Or Any Other Complex And Overt Behavior. Predisposition Via A Long Chain Of Complex Chemical Reactions, Mediated Through A More Complex Series Of Life's Circumstances, Does Not Equal Identification Or Even Causation.

Speciation Does Not Necessarily Promote Evolutionary Change; Rather, Speciation 'gathers In' And Guards Evolutionary Change By Locking And Stabilization For Sufficient Geological Time Within A Darwinian Individual Of The Appropriate Scale. If A Change In A Local Population Does Not Gain Such Protection, It Becomes-to Borrow Dawkins's Metaphor At A Macroevolutionary Scale-a Transient Duststorm In The Desert Of Time, A Passing Cloud Without Borders, Integrity, Or Even The Capacity To Act As A Unit Of Selection, In The Panorama Of Life's Phylogeny.

An Old Paleontological In Joke Proclaims That Mammalian Evolution Is A Tale Told By Teeth Mating To Produce Slightly Altered Descendant Teeth.

In Our Struggle To Understand The History Of Life, We Must Learn Where To Place The Boundary Between Contingent And Unpredictable Events That Occur But Once And The More Repeatable, Lawlike Phenomenon That May Pervade Life's History As Generalities.

Natural Selection May Lead To Benefits For Species, But These `higher' Advantages Can Only Arise As Sequelae, Or Side Consequences, Of Natural Selection's Causal Mechanism: Differential Reproductive Success Of Individuals.

[t]he Effects Of General Change [in Literature] Are Most Tellingly Recorded Not In Alteration Of The Best Products, But In The Transformation Of The Most Ordinary Workaday Books; For When Potboilers Adopt The New Style, Then The Revolution Is Complete.

Each Of The Major Sciences Has Contributed An Essential Ingredient In Our Long Retreat From An Initial Belief In Our Own Cosmic Importance. Astronomy Defined Our Home As A Small Planet Tucked Away In One Corner Of An Average Galaxy Among Millions; Biology Took Away Our Status As Paragons Created In The Image Of God; Geology Gave Us The Immensity Of Time And Taught Us How Little Of It Our Own Species Has Occupied.

Ordinary Speciation Remains Fully Adequate To Explain The Causes And Phenomenology Of Punctuation.

Contrary To Current Cynicism About Past Golden Ages, The Abstraction Known As 'the Intelligent Layperson' Does Exist - In The Form Of Millions Of Folks With A Passionate Commitment To Continuous Learning.

Good Scholars Struggle To Understand The World In An Integral Way (pedants Bite Off Tiny Bits And Worry Them To Death). These Visions Of Reality [...] Demand Our Respect, For They Are An Intellectual's Only Birthright. They Are Often Entirely Wrong And Always Flawed In Serious Ways, But They Must Be Understood Honorably And Not Subjected To Mayhem By The Excision Of Patches.

Few Tragedies Can Be More Extensive Than The Stunting Of Life, Few Injustices Deeper Than The Denial Of An Opportunity To Strive Or Even To Hope, By A Limit Imposed From Without, But Falsely Identified As Lying Within.

I Would Trade All The Advantages Of Humanity To Be A Fly On The Wall When Franklin And Jefferson Discussed Liberty, Lenin And Trotsky Revolution, Newton And Halley The Shape Of The Universe, Or When Darwin Entertained Huxley And Lyell At Down.

Contingency Is A Thing Unto Itself, Not The Titration Of Determinism By Randomness.

In Science, 'fact' Can Only Mean 'confirmed To Such A Degree That It Would Be Perverse To Withhold Provisional Assent.' I Suppose That Apples Might Start To Rise Tomorrow, But The Possibility Does Not Merit Equal Time In Physics Classrooms.

Pictures Are Not Incidental Frills To A Text; They Are Essences Of Our Distinctive Way Of Knowing.

Each Worldview Was A Cultural Product, But Evolution Is True And Separate Creation Is Not. [...] Worldviews Are Social Constructions, And They Channel The Search For Facts. But Facts Are Found And Knowledge Progresses, However Fitfully. Fact And Theory Are Intertwined, And All Great Scientists Understand The Interaction.

Guessing Right For The Wrong Reason Does Not Merit Scientific Immortality.

Asian Homo Erectus Died Without Issue And Does Not Enter Our Immediate Ancestry (for We Evolved From African Populations); Neanderthal People Were Collateral Cousins, Perhaps Already Living In Europe While We Emerged In Africa... In Other Words, We Are An Improbable And Fragile Entity, Fortunately Successful After Precarious Beginnings As A Small Population In Africa, Not The Predictable End Result Of A Global Tendency. We Are A Thing, An Item Of History, Not An Embodiment Of General Principles.

Our World Is Not An Optimal Place, Fine Tuned By Omnipotent Forces Of Selection. It Is A Quirky Mass Of Imperfections, Working Well Enough (often Admirably); A Jury-rigged Set Of Adaptations Built Of Curious Parts Made Available By Past Histories In Different Contexts. A World Optimally Adapted To Current Environments Is A World Without History, And A World Without History Might Have Been Created As We Find It. History Matters; It Confounds Perfection And Proves That Current Life Transformed Its Own Past.

[in Natural History,] Great Discovery Often Requires A Map To A Hidden Mine Filled With Gems Then Easily Gathered By Conventional Tools, Not A Shiny New Space-age Machine For Penetrating Previously Inaccessible Worlds.

Precise Adaptation, With Each Part Finely Honed To Perform A Definite Function In An Optimal Way, Can Only Lead To Blind Alleys, Dead Ends, And Extinction.

How Did Scientists Get Money In The Past? They Were Either Lucky And Independently Wealthy, Like Darwin, Or They Had Patrons, Like Galileo. Universities Or Governments Have Become Patrons Only In The Last Few Generations. Many Of The Great Scientists Of The Past Were In Debt To Their Patrons In The Same Sense That Modern Scientists Are Influenced By What Their Granting Agencies Want.

At A Minimum, In Explaining Evolutionary Pathways Through Time, The Constraints Imposed By History Rise To Equal Prominence With The Immediate Advantages Of Adaptation.

Sigmund Freud Often Remarked That Great Revolutions In The History Of Science Have But One Common, And Ironic, Feature: They Knock Human Arrogance Off One Pedestal After Another Of Our Previous Conviction About Our Own Self-importance.

But If We Laugh With Derision, We Will Never Understand. Human Intellectual Capacity Has Not Altered For Thousands Of Years So Far As We Can Tell. If Intelligent People Invested Intense Energy In Issues That Now Seem Foolish To Us, Then The Failure Lies In Our Understanding Of Their World, Not In Their Distorted Perceptions.

Darwinian Evolution May Be The Most Truthful And Powerful Idea Ever Generated By Western Science, But If We Continue To Illustrate Our Conviction With An Indefensible, Unsupported, Entirely Speculative, And Basically Rather Silly Story, Then We Are Clothing A Thing Of Beauty In Rags - And We Should Be Ashamed, "for The Apparel Oft Proclaims The Man.

The Argument That The Literal Story Of Genesis Can Qualify As Science Collapses On Three Major Grounds: The Creationists' Need To Invoke Miracles In Order To Compress The Events Of The Earth's History Into The Biblical Span Of A Few Thousand Years; Their Unwillingness To Abandon Claims Clearly Disproved, Including The Assertion That All Fossils Are Products Of Noah's Flood; And Their Reliance Upon Distortion, Misquote, Half-quote, And Citation Out Of Context To Characterize The Ideas Of Their Opponents.

In His Anti-darwinian Book... (and Eponymously Named The Neck Of The Giraffe ), Francis Hitching Tells The Story... "the Need To Survive By Reaching Ever Higher For Food Is, Like So Many Darwinian Explanations Of Its Kind, Little More Than A Post Hoc Speculation." Hitching Is Quite Correct, But He Rebuts A Fairy Story That Darwin Was Far Too Smart To Tell - Even Though The Tale Later Entered Our High School Texts As A "classic Case" Nonetheless.

Acquired Characteristics Are Inherited In Technology And Culture. Lamarckian Evolution Is Rapid And Accumulative. It Explains The Cardinal Difference Between Our Past, Purely Biological Mode Of Change, And Our Current, Maddening Acceleration Toward Something New And Liberating- Or Toward The Abyss.

I Was Lucky To Wander Into Evolutionary Theory, One Of The Most Exciting And Important Of All Scientific Fields. I Had Never Heard Of It When I Started At A Rather Tender Age; I Was Simply Awed By Dinosaurs. I Thought Paleontologists Spent Their Lives Digging Up Bones And Putting Them Together, Never Venturing Beyond The Momentous Issue Of What Connects To What. Then I Discovered Evolutionary Theory. Ever Since Then, The Duality Of Natural History-richness In Particularities And Potential Union In Underlying Explanation-has Propelled Me.

Facts And Theories Are Different Things, Not Rungs In A Hierarchy Of Increasing Certainty. Facts Are The World's Data. Theories Are Structures Of Ideas That Explain And Interpret Facts. Facts Do Not Go Away While Scientists Debate Rival Theories For Explaining Them. Einstein's Theory Of Gravitation Replaced Newton's, But Apples Did Not Suspend Themselves In Mid-air Pending The Outcome.

The Modern Theory Of Evolution Does Not Require Gradual Change. It In Fact, The Operation Of Darwinian Processes Should Yield Exactly What We See In The Fossil Record. It Is Gradualism That We Must Reject, Not Darwinism.

Theory Of Evolution

Even The Standard Example Of Ancient Nonsense - The Debate About Angels On Pinheads - Makes Sense Once You Realize That Theologians Were Not Discussing Whether Five Or Eighteen Would Fit, But Whether A Pin Could House A Finite Or An Infinite Number.

Before Kuhn, Most Scientists Followed The Place-a-stone-in-the-bright-temple-of-knowledge Tradition, And Would Have Told You That They Hoped, Above All, To Lay Many Of The Bricks, Perhaps Even The Keystone, Of Truth's Temple. Now Most Scientists Of Vision Hope To Foment Revolution. We Are, Therefore, Awash In Revolutions, Most Self-proclaimed.

The Pathways That Have Led To Our Evolution Are Quirky, Improbable, Unrepeatable And Utterly Unpredictable.

A Rare Book At Once Of Great Importance And Wonderful To Read.... Gould Presents A Fascinating Historical Study Of Scientific Racism, Tracing It Through Monogeny And Polygeny, Phrenology , Recapitulation, And Hereditarian Iq Theory. He Stops At Each Point To Illustrate Both The Logical Inconsistencies Of The Theories And The Prejudicially Motivated, Albeit Unintentional, Misuse Of Data In Each Case.... A Major Addition To The Scientific Literature.

The More Important The Subject And The Closer It Cuts To The Bone Of Our Hopes And Needs, The More We Are Likely To Err In Establishing A Framework For Analysis.

I View The Major Features Of My Own Odyssey As A Set Of Mostly Fortunate Contingencies. I Was Not Destined By Inherited Mentality Or Family Tradition To Become A Paleontologist. I Can Locate No Tradition For Scientific Or Intellectual Careers Anywhere On Either Side Of My Eastern European Jewish Background. I View My Serious And Lifelong Commitment To Baseball In Entirely The Same Manner: Purely As A Contingent Circumstance Of Numerous, Albeit Not Entirely Capricious, Accidents.

Facts Do Not 'speak For Themselves'; They Are Read In The Light Of Theory.

Evolution Has Encountered No Intellectual Trouble; No New Arguments Have Been Offered. Creationism Is A Home-grown Phenomenon Of American Sociocultural History-a Splinter Movement ... Who Believe That Every Word In The Bible Must Be Literally True, Whatever Such A Claim Might Mean.

History Employs Evolution To Structure Biological Events In Time.

The Fundamentalists, By 'knowing' The Answers Before They Start, And Then Forcing Nature Into The Straitjacket Of Their Discredited Preconceptions, Lie Outside The Domain Of Science - Or Any Honest Intellectual Inquiry.

The Theory Of Punctuated Equilibrium, Proposed By Niles Eldredge And Myself, Is Not, As So Often Misunderstood, A Radical Claim For Truly Sudden Change, But A Recognition That Ordinary Processes Of Speciation, Properly Conceived As Glacially Slow By The Standard Of Our Own Life-span, Do Not Resolve Into Geological Time As Long Sequences Of Insensibly Graded Intermediates (the Traditional, Or Gradualistic, View), But As Geologically "sudden" Origins At Single Bedding Planes.

I Have Often Been Amused By Our Vulgar Tendency To Take Complex Issues, With Solutions At Neither Extreme Of A Continuum Of Possibilities, And Break Them Into Dichotomies, Assigning One Group To One Pole And The Other To An Opposite End, With No Acknowledgment Of Subtleties And Intermediate Positions And Nearly Always With Moral Opprobrium Attached To Opponents.

Science Is Not 'organized Common Sense'; At Its Most Exciting, It Reformulates Our View Of The World By Imposing Powerful Theories Against The Ancient, Anthropocentric Prejudices That We Call Intuition.

Surely The Mitochondrion That First Entered Another Cell Was Not Thinking About The Future Benefits Of Cooperation And Integration; It Was Merely Trying To Make Its Own Living In A Tough Darwinian World

Results Rarely Specify Their Causes Unambiguously. If We Have No Direct Evidence Of Fossils Or Human Chronicles, If We Are Forced To Infer A Process Only From Its Modern Results, Then We Are Usually Stymied Or Reduced To Speculation About Probabilities. For Many Roads Lead To Almost Any Rome.

A Lot Of Scientists Hate Writing. Most Scientists Love Being In The Lab And Doing The Work And When The Work Is Done, They Are Finished.

I Am Glad That The Life Of Pandas Is So Dull By Human Standards, For Our Efforts At Conservation Have Little Moral Value If We Preserve Creatures Only As Human Ornaments; I Shall Be Impressed When We Show Solicitude For Warty Toads And Slithering Worms.

No One Should Feel At All Offended Or Threatened By The Obvious Fact That We Are Not All Born Entirely Blank, Or Entirely The Same, In Our Mixture Of The Broad Behavioral Propensities Defining What We Call "temperament".

Phony Psychics Like Uri Geller Have Had Particular Success In Bamboozling Scientists With Ordinary Stage Magic, Because Only Scientists Are Arrogant Enough To Think That They Always Observe With Rigorous And Objective Scrutiny, And Therefore Could Never Be So Fooled While Ordinary Mortals Know Perfectly Well That Good Performers Can Always Find A Way To Trick People.

I'm Not A Great Deductive Thinker, But I Will Admit To Having Competence In A Very Wide Range Of Things - Not Being Afraid To Try To Write About Baseball, Choral Music And Dinosaurs In The Same Week And See Connections Among Them.

In What I Like To Call The Great Asymmetry, Every Spectacular Incident Of Evil Will Be Balanced By 10,000 Acts Of Kindness, Too Often Unnoted And Invisible.

Most Books, After All, Are Ephemeral; Their Specifics, Several Years Later, Inspire About As Much Interest As Daily Battle Reports From The Hundred Years' War.

... No Compelling Data To Support Its Anachronistic Social Darwinism.

In Their Recently Aborted Struggle To Inject Genesis Literalism Into Science Classrooms, Fundamentalist Groups Followed Their Usual Opportunistic Strategy Of Arguing Two Contradictory Sides Of A Question When A Supposed Rhetorical Advantage Could Be Extracted From Each.

The Facts Of Nature Are What They Are, But We Can Only View Them Through The Spectacles Of Our Mind. Our Mind Works Largely By Metaphor And Comparison, Not Always (or Often) By Relentless Logic. When We Are Caught In Conceptual Traps, The Best Exit Is Often A Change In Metaphor Not Because The New Guideline Will Be Truer To Nature (for Neither The Old Nor The New Metaphor Lies "out There" In The Woods), But Because We Need A Shift To More Fruitful Perspectives, And Metaphor Is Often The Best Agent Of Conceptual Transition.

The Silliest And Most Tendentious Of Baseball Writing Tries To Wrest Profundity From The Spectacle Of Grown Men Hitting A Ball With A Stick By Suggesting Linkages Between The Sport And Deep Issues Of Morality, Parenthood, History, Lost Innocence, Gentleness, And So On, Seemingly Ad Infinitum . (the Effort Reeks Of Silliness Because Baseball Is Profound All By Itself And Needs No Excuses; People Who Don't Know This Are Not Fans And Are Therefore Unreachable Anyway.

Wind Back The Tape Of Life To The Early Days Of The Burgess Shale; Let It Play Again From An Identical Starting Point, And The Chance Becomes Vanishingly Small That Anything Like Human Intelligence Would Grace The Replay.

As A Word, Ecology Has Been So Debased By Recent Political Usage That Many People Employ It To Identify Anything Good That Happens Far From Cities And Without Human Interference.

If I Have Any Insight At All To Contribute It Is This: Find Out What You Are Really Good At And Stick To It.

When People Learn No Tools Of Judgment And Merely Follow Their Hopes, The Seeds Of Political Manipulation Are Sown.

Scientists Have Power By Virtue Of The Respect Commanded By The Discipline... We Live With Poets And Politicians, Preachers And Philosophers. All Have Their Ways Of Knowing, And All Are Valid In Their Proper Domain. The World Is Too Complex And Interesting For One Way To Hold All The Answers.

I Despair Of Persuading People To Drop The Familiar And Comforting Tactic Of Dichotomy. Perhaps, Instead, We Might Expand The Framework Of Debates By Seeking Other Dichotomies More Appropriate Than, Or Simply Different From, The Conventional Divisions. All Dichotomies Are Simplifications, But The Rendition Of A Conflict Along Differing Axes Of Several Orthogonal Dichotomies Might Provide An Amplitude Of Proper Intellectual Space Without Forcing Us To Forgo Our Most Comforting Tool Of Thought.

If We Make This Readjustment To View Homo Sapiens As An Ultimate In Oddball Rarity, And Life At Bacterial Grade As The Common Expression Of A Universal Phenomenon, Then We Could Finally Ask The Truly Fundamental Question Raised By The Prospect Of Martian Fossils. If Life Originates As A General Property Of The Material Universe Under Certain Conditions (probably Often Realized), Then How Much Can The Basic Structure And Constitution Of Life Vary From Place To Independent Place?

People Talk About Human Intelligence As The Greatest Adaptation In The History Of The Planet. It Is An Amazing And Marvelous Thing, But In Evolutionary Terms, It Is As Likely To Do Us In As To Help Us Along.

Rifkin's Assertions Bear No Relationship To What I Have Observed And Practiced For 25 Years ... Either I Am Blind Or He Is Wrong - And I Think I Can Show, By Analyzing His Slipshod Scholarship And Basic Misunderstanding Of Science, That His World Is An Invention Constructed To Validate His Own Private Hopes ... Rifkin Shows No Understanding Of The Norms And Procedures Of Science: He Displays Little Comprehension Of What Science Is And How Scientists Work.

The Origin Of Homo Sapiens, As A Tiny Twig On An Improbable Branch Of A Contingent Limb On A Fortunate Tree, Lies Well Below The Boundary.

Since The Universe Must Contain Millions Of Appropriate Planets, Consciousness In Some Form - But Not With The Paired Eyes And Limbs, And The Brain Built Of Neurons In The Only Example We Know - May Evolve Frequently. But If Only One Origin Of Life In A Million Ever Leads To Consciousness, Then Martian Bacteria Most Emphatically Do Not Imply Little Green Men.

Historical Science Is Not Worse, More Restricted, Or Less Capable Of Achieving Firm Conclusions Because Experiment, Prediction, And Subsumption Under Invariant Laws Of Nature Do Not Represent Its Usual Working Methods. The Sciences Of History Use A Different Mode Of Explanation, Rooted In The Comparative And Observational Richness In Our Data. We Cannot See A Past Event Directly, But Science Is Usually Based On Inference, Not Unvarnished Observation (you Don't See Electrons, Gravity, Or Black Holes Either).

Antiessentialist Thinking Forces Us To View The World Differently. We Must Accept Shadings And Continua As Fundamental. We Lose Criteria For Judgment By Comparison To Some Ideal: Short People, Retarded People, People Of Other Beliefs, Colors, And Religions Are People Of Full Status.

Science Is All Those Things Which Are Confirmed To Such A Degree That It Would Be Unreasonable To Withhold One's Provisional Consent.

The Proof Of Evolution Lies In Those Adaptations That Arise From Improbable Foundations.

Is Uniformitarianism Necessary?

The World, Unfortunately, Rarely Matches Our Hopes And Consistently Refuses To Behave In A Reasonable Manner.

South America Had Been An Island Continent, Far Bigger And Far More Diverse Than Australia, For Tens Of Millions Of Years Before The Isthmus Of Panama Rose Just A Couple Of Million Years Ago. The Resulting Flood Of North American Mammals Across The New Land Bridge Corresponds In Time With The Decimation Of The Native South American Fauna. In Fact, Most Large Mammals Generally Considered Distinctly South American... Are All Recent Migrants From North America.

We Must [it Has Been Arued] Go Beyond Reductionism To A Holistic Recognition That Biology And Culture Interpenetrate In An Inextricable Manner.

Anything, Even The Conceptually Most Complex Material, Can Be Written For General Audiences Without Any Dumbing Down. Of Course You Have To Explain Things Carefully. This Goes Back To Galileo, Who Wrote His Great Books As Dialogues In Italian, Not As Treatises In Latin. And To Darwin, Who Wrote The Origin Of Species For General Readers. I Think A Lot Of People Pick Up Darwin's Book And Assume It Must Be A Popular Version Of Some Technical Monograph, But There Is No Technical Monograph. That's What He Wrote. So What I'm Doing Is Part Of A Great Humanistic Tradition.

Evolution Is An Inference From Thousands Of Independent Sources, The Only Conceptual Structure That Can Make Unified Sense Of All This Disparate Information.

If You Defend A Behavior By Arguing That People Are Programmed Directly For It, Then How Do You Continue To Defend It If Your Speculation Is Wrong, For The Behavior Then Becomes Unnatural And Worthy Of Condemnation. Better To Stick Resolutely To A Philosophical Position On Human Liberty: What Free Adults Do With Each Other In Their Own Private Lives Is Their Business Alone. It Need Not Be Vindicated And Must Not Be Condemned By Genetic Speculation.

People Are Storytelling Creatures. We Like Stories That Go Somewhere, And Therefore We Like Trends - Because Trends Are Things That Either Get Better Or Get Worse, So We Can Either Rejoice Or Lament. But We Mistakenly Depict Many Things As Trends Moving In Some Direction. We Take The "full House" Of Variation In A System And Try To Represent It As A Single Number, When In Fact What We Should Be Doing Is Studying The Variation As It Expands And Contracts. If You Look At The History Of The Variation In All Its Complexity, Then You See There's No Trend.

Very Little Comes Easily To Our Poor, Benighted Species (the First Creature, After All, To Experiment With The Novel Evolutionary Inventions Of Self-conscious Philosophy And Art). Even The Most "obvious," "accurate," And "natural" Style Of Thinking Or Drawing Must Be Regulated By History And Won By Struggle. Solutions Must Therefore Arise Within A Social Context And Record The Complex Interactions Of Mind And Environment That Define The Possibility Of Human Improvement.

Humans Arose ... As A Fortuitous And Contingent Outcome Of Thousands Of Linked Events, Any One Of Which Could Have Occurred Differently And Sent History On An Alternative Pathway That Would Not Have Led To Consciousness.

Still, Our Creationist Incubi, Who Would Never Let Facts Spoil A Favorite Argument, Refuse To Yield, And Continue To Assert The Absence Of All Transitional Forms By Ignoring Those That Have Been Found, And Continuing To Taunt Us With Admittedly Frequent Examples Of Absence.

The Absence Of Fossil Evidence For Intermediary Stages Between Major Transitions In Organic Design, Indeed Our Inability, Even In Our Imagination, To Construct Functional Intermediates In Many Cases, Has Been A Persistent And Nagging Problem For Gradualist Accounts Of Evolution.

We Are The Accidental Result Of An Unplanned Process ... The Fragile Result Of An Enormous Concatenation Of Improbabilities, Not The Predictable Product Of Any Definite Process.

...we Must Be Wary Of Granting Too Much Power To Natural Selection By Viewing All Basic Capacities Of Our Brain As Direct Adaptations.

Organisms [...] Are Directed And Limited By Their Past. They Must Remain Imperfect In Their Form And Function, And To That Extent Unpredictable Since They Are Not Optimal Machines. We Cannot Know Their Future With Certainty, If Only Because A Myriad Of Quirky Functional Shifts Lie Within The Capacity Of Any Feature, However Well Adapted To A Present Role.

Perhaps I Am Just A Hopeless Rationalist, But Isn't Fascination As Comforting As Solace? Isn't Nature Immeasurably More Interesting For Its Complexities And Its Lack Of Conformity To Our Hopes? Isn't Curiosity As Wondrously And Fundamentally Human As Compassion?

People May Believe Correct Things For The Damndest And Weirdest Of Wrong Reasons.

Charles Darwin Viewed The Fossil Record More As An Embarrassment Than As An Aid To His Theory.
